Description of the Related Art As shown in FIG. 5 , a conventional slit device comprises a board formed of a foamed synthetic resin into an appropriately sized rectangular plate, jointing materials provided on both sides of the board, and one side of the board. And a support arm for supporting and fixing the abutment plate. At the time of formwork construction, first, the jointing material is fixed to the inside of the outer wall formwork by nailing, and one side of the slit to which the patch plate is attached is attached to the jointing material in advance. Next, one of the pair of support arms is hooked to the separator fixed at an appropriate position on the wall formwork, and the other is supported and fixed by hooking a backing plate. Furthermore, after building the inner wall formwork to which the joint material to be attached to the other side of the slit is nailed inside so that the slit material and the joint material can be attached, concrete is poured from the column side, and then It was cast on the wall side. Further, as shown in JP-A-08-93266, a reinforcing layer is provided on a foamed synthetic resin board to reinforce the board itself and to be fixed to a wall form, which can be attached to both sides of the board. Discloses a slitting device that does not use a reinforcing backing plate and a supporting arm that supports the backing plate.

Backing plates and supporting arms that support them must be used as reinforcements so that the board can withstand the lateral pressure when placing concrete, and when installing them, fix the supporting arms Consideration has to be given to the mounting position of the separator, which requires labor and cost. In the concrete casting, it is necessary to first perform the work from the pillar side, which is the reinforcing direction, and then to the wall side, which is very troublesome.

の問題が発生するのである。In the case of Japanese Patent Application Laid-Open No. 08-93266, a reinforcing material such as a backing plate is not required, and the labor of concrete placing procedure is eliminated. However, it may not be used depending on the method of finishing the concrete surface. Depending on the structural design, the method of installing the slit may cause the concrete wall to be completely broken or partially broken. Also, due to the design of the design, finishing of the concrete surface of the part where the slit is buried, for example, when forming a groove-shaped or flat joint, or inside the wall (room side), joints are required. Sometimes not. The slit of the present invention uses a synthetic foam resin board, and on its surface, a reinforcing layer that resists tension is reinforced by providing it with paper or synthetic foam resin, and by attaching jointing materials to both sides, Although it has a structure that can withstand the lateral pressure of concrete, the board is made of synthetic foam resin, so the strength in the shear direction and the holding power of nails are weak, so the board can not be fixed directly to the formwork by nailing . That is, when joints are not required on the concrete surface, the board cannot be directly fixed to the formwork, which causes a problem that the board cannot be used.

There is no need for a reinforcement such as a plate for the lateral pressure of concrete. Compared to foam synthetic resin boards, the strength in the shear direction and the holding power of the nails driven are stronger, so nailing is possible, and it is compatible with various methods without being limited to the concrete surface finishing method For example, the conventional problems described above can be solved.
